In referring to the accompanying drawing, reference will first be made to the type of socket shown in Figs. 1 to 4 inclusive wherein the numeral 5 designates the body portion or insulator of a wall socket which is of substantially cylindrical formation. The front face of the body portion or insulater 5 is designated by the reference numeral 6 and is surrounded by the annular bead or flange 7. In Figs. 2 and 3 the rear face 8 of the member 5 is illustrated as having formed therein the arcuate grooves 9 having the lateral extensions 10 formed at the opposite ends thereof and extending to the periphery of the body portion. These extensions 10 and arcuate grooves 9 are provided for accommodating circuit wires and will permit the body portion or. insulator 5 to be mounted upon a wall or other surface with the rear face 8 flushly engaging the same by any suitable fastening means which may be inserted through the apertures 11.

Arranged in a circular series around the axis of the body portion or insulator 5 are the diametrically opposed openings 12 which are of rectangular formation in cross-section and the diametrically opposed openings 13 which are of circular or cylindrical formationv in cross-sectionand are arranged at right angles to the openings 12. The front face 6 of the body portion or insulator 5 is countersunk at the two points designated by the reference numerals 14, which countersunk portions are concentric with the cylindrical openings 13. The rear face 8 of the body portion or insulator 5 is cut away at the two places 15 in a manner to connect or form communication between the arcuate grooves 9 and the inner ends of the openings 12 and 13.

tion 18 carried by an inverted U-shaped strip in Fl 3 to inclusive.

19 or a strip bent upon itself at 20. The plate-like porti n 16 is suitably agertured for permitting the tubular member 21 to be connected thereto. ll :l r ther aperture is formed in the outer end PO} in of this plate 16 and intended to receive the wire connecting screw 22 which is employed tor est:,:.l' lishing a connection between a line wire and nal members 19 and 21. By

tne term in-SjCCtillg Fig. 2, it will be seen that the ends of the tubular connector 21 are cl or bent outwardly tor fastening the i e structure shown in Fig. 4 to the body portion or insulator the said tubular terminal member 21 being received within a opening 13 n the mer ibei The bony portion or in. ator 5 is further provided with a socket 23 for loosely receiving the inner end of the connector screw 22. By inspect- 1 and 3, it will be seen that the plate member 16 and lateral projection 17 are received within the cutaway portion '1 led in the rear face 8 of the member 5 and when arranged in this cutaway portion, the inverted L -shaped contact or termii'ial 19 wll project through an opening 12 for pres ting the bent end 20 ot the same to the nt face G or the body portion 5.

It will now be seen that a plug-in member carrying two male cylindrical termirals may be connected to the conductor plates 16 by having the terminals inserted into the bores ot the tubular terminals 21 and, also, that a plug-in. member having a pair of male blade. terminals may be connected to the plates 16 by insertng the terminals into the openings 12 t the element 5, the strips 19 being of a suitable resilient nature to yield or permit being compressed to allow the entrance of these male blade terminals.

The plug socket illustrated in detail in Figs. 5 to 12 inclusive includes a substantially cylii'idrically-shaped body portion or insulator 24 which has the reduced inner end portion 24 Arranged in substantially circular series and extending longitudinally thru the body portion 24' are the dian'ietrien tro ca-lly opposed openings which are of rec tangular formation in cross-s .ction and the d metrically opp sed openings 26 which are of circular formation in cross-section and are arranged at right angles to the openings 25. The reduced end portion 24 of the insulator 24 is provided with longitudinally extending grooves or recess 27 which are extensions of the openings and the longitudinally extending grooves or recesses 28 which are entensions of tie circular openings 23. The free end 29 01" the reduced end portion 24 ot substantially conical formation with the flattened. end 29. The reduced end portion 24? is grooved at 30, as best illustrated in these same figures, and also in Fig. 6, i l t' 29"llt d h fo Ll1 comca p01 ion. is 1 us rate as oi 111 formed thereon the axially extending tits 31. Surrounding the reduced portion 24 is athin metallic ring 32 which is formed with a spiral thread and has its inner edge bent innardly to be received within the groove 30 for fastening the ring upon the reduced end portion. in Fig. 6 the outer edge of the ring 32 is illustrated as being bent inwardly at 34 and as having diametrically opposed notches 35 formed therein for receivin the tits 3i. :lormed on the conical end 29 or the insulator The reception of these tits 31 in the notches 35 will prevent the ring 32 from rotating about the reduced end 24*.

In Fig. 11 there are shown two female, cylindrical terminals 36 and 37. The terminal 36 is formed with a tongue 38 which is apertured tor the reception of a rivet 39, see Fig. 9. This cylindrical terminal 36 is intended to be inserted in one of the openings 26 and to be connected to the threaded ring 32 by the rivet 39. The remaining end of this member 36 is flanged at 40, as best illustrated in Figs. 9 and 11. It will be seen that this member 36 also functions to prevent the ring 32 from being removed from the reduced end and, further, from rotating about this end portion. The cylindrical terminal 37 is formed with a ribbonlilre extension 41 which is bent at an obtuse angle to form the portion 42 having at its free end the laterally extending apertured car 43. This member 37 is intended to be received within the remaining opening 26 and the ribbon like extension 42 is received within the adjacent groove 28 .so that it will not contact with the ring 32. The apertured car 43 flushly engages the flattened end 29. of the conical end portion 29 and is secured thereto by the rivet 44, best shown in Figs. 9 and 10.

In Fig. 11 there is shown a terminal formed from a suitable strip of metal and having the Ushaped contact portion 45, the stem 46, and the bent over ear portion 47 which is apertured for receiving the rivet- 48 employed for fastening this apertured car 47 to the ring 32. Figure 10 shows this member received within one of the openings 25 formed in the body portion or insulator 24. Figure 12 further illustrates a terminal formed from a strip of metal and including the U-shaped contact portion 49, the stem 50, and the apertured ear 51. Fig. 10 also shows this terminal member received within the remaining opening 25 with the apertured ear held in flush engagement with the flattened end 29 of the insulator 24 by the previously referred to rivet 44.

It will now be seen that the terminal members" 36 and 45 are connected in parallel to the ring 32 while the terminal members 3'7 and 49 are electrically connected'together by the rivet 44.

may be employed for having connected thereto a plug-in member provided with a pair of cylindrical, male terminals or a pair of blades, male terminals in the same manner as described in connection withthe wall socket shown in Figs. 1 to 4c inclusive.

It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
